   You copy something like superlu.py to mkl.py and edit that.  

    PETSc automatically loads up all the files in the config/PETSc/packages directory so you don't have to list your new file anywhere in setup dependencies or anything

    Nope

The thing is that when I'm compiling the variable PETSC_HAVE_PACKAGE doesn't show up, I guess that means the variable is 0 or something else happens, and my code is not going to be compile. So if you could give some ideas of why Petsc doesn't compile my code.
